The Effects of Resistance Training on Health of Children and Adolescents With Disabilities

Consensus-based recommendations for the rehabilitation of children with arthrogryposis multiplex congenita: an integrated knowledge translation approach

BACKGROUND

Arthrogryposis multiplex congenita (AMC) is a group of rare disorders characterized by multiple joint contractures present at birth. Early rehabilitation is essential to minimize joint contractures and maximize autonomy and participation among individuals with AMC. However, there is little robust scientific evidence to inform best practice. This project aimed to develop consensus-based recommendations for the rehabilitation management of children with AMC in the following priority areas: early intervention and motor development, muscle and joint function, orthotics, mobility, participation in areas of life, pain, psychosocial wellbeing, and perioperative rehabilitation.

RESULTS

This multi-phase project used an integrated knowledge translation approach. Based on the results from scoping reviews on the priority areas identified for the rehabilitation of children with AMC, and a clinician survey describing current practices in AMC rehabilitation, three panels of expert clinicians in occupational therapy, physical therapy, orthopedics, physiatry, and social work, as well as people with lived experience and researchers from 10 countries developed consensus-based recommendations for rehabilitation, in concordance with the Grading of Recommendations, Assessment, Development and Evaluations framework (GRADE) criteria. A modified Delphi process was completed with a wider group of international AMC experts to revise and validate the recommendations (Round 1 = 41 and Round 2 = 37 experts). A five-member external review panel appraised the recommendations using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool. The final 16 recommendations reached a mean agreement rate of 96.6% after two Delphi rounds. The overall quality was rated at 96.6% on the AGREE II tool. Interviews with clinicians and managers identified facilitators and barriers to implementation of the recommendations in practice using the Theoretical Domain Framework.

CONCLUSION

Consensus-based, expert validated recommendations for the rehabilitation of children with AMC were developed by a wide range of stakeholders, healthcare users and providers. The proposed recommendations are expected to contribute to improving child- and family-centered practice and health outcomes. Future work includes a knowledge translation strategy to promote sharing and implementation of the recommendations in practice.

Factors Associated With Depression in Caregivers of Adults With Down Syndrome

BACKGROUND

Family caregivers of those with developmental disabilities have higher rates of depression and anxiety compared with caregivers of those without development disability. Few studies have examined factors that contribute to caregiver depression, including the appraisal of caregiving responsibilities and the physical fitness and daily function of the care recipient. The purpose of this study was to identify intrapersonal (caregiver) and interpersonal (care recipient) factors associated with depressive symptoms in caregivers of adults with Down syndrome (DS).

METHODS

Twenty-four adults with DS participating in a 12-month physical activity trial completed physical fitness and function tests (VO2peak, hand grip strength, timed up and go, five times sit to stand) and activities of daily living (ADL) surveys at their baseline visit. Caregivers (n = 24) of the adults with DS completed surveys on caregiving distress, quality of life (QoL) and depressive symptoms. We evaluated the associations of these assessments on caregiver depressive symptoms using Mann-Whitney U tests and Spearman correlations.

RESULTS

Adults with DS were 23 ± 7.5 years, 58% female; caregivers were 54 ± 10 years, 100% female, 96% family members. Caregiver depressive symptoms were significantly associated with caregiving distress (p = 0.024) and caregiving QoL (r = -0.58, p = 0.003). Hand grip strength of care recipients was inversely correlated with caregiver depressive symptoms (r = -0.45, p = 0.03), but other assessments of physical function and ADL were not associated with caregiver depressive symptoms.

CONCLUSIONS

Caregiver depressive symptoms were related to modifiable factors related to the caregiver and care recipient. Intervening to improve caregiving appraisal and functional strength of the care recipient may positively impact caregiver mental health.

Comparison of Participation in Strength Activity Among People With and Without Disabilities: 2013-2017 Behavioral Risk Factor Surveillance System

BACKGROUND

The current physical activity guidelines recommend engagement in strength activities at least 2 days per week. Currently, there is a lack of literature examining strength activities among people with disabilities. The purpose of this study is to estimate and compare the prevalence of engagement in strength activities and adherence to strength activity guidelines among adults with and without disabilities in the United States.

METHODS

A total of 1,005,644 adults (18-80 y old) with and without disabilities from the 2013 to 2017 Behavioral Risk Factor Surveillance System were included in this secondary data analysis. Descriptive analyses were performed to describe the prevalence of strength activity behaviors of adults with and without disabilities. Logistic and Poisson regression models were performed to evaluate the relative contribution of disability status on strength activity behaviors.

RESULTS

A higher proportion of participants without disabilities (46.42%, 95% CI, 46.18-46.65) reported engaging in strength activities compared with participants with disabilities (30.68%, 95% CI, 30.29-31.08; P < .01). Participants with disabilities were less likely to engage in strength activities (odds ratio = 0.51, 95% CI, 0.50-0.52; adjusted odds ratio = 0.75, 95% CI, 0.73-0.77) and meet strength activity guidelines (odds ratio = 0.56, 95% CI, 0.54-0.57; adjusted odds ratio = 0.75, 95% CI, 0.73-0.77) than participants without disabilities.

CONCLUSION

Experiencing a disability is associated with lower engagement in strength activities; thus, it is important to identify effective and efficient approaches to promoting strength activities among people with disabilities.

Effects of exercise, physical activity, and sports on physical fitness in adults with Down syndrome: A systematic review

This systematic review aimed to analyze the effects of exercise, physical activity, and sports on physical fitness in adults with Down syndrome (DS). A literature search was conducted across four databases EBSCO, Scopus, Web of Science, and PubMed. The PRISMA guidelines were followed. The PEDro scale and the Cochrane risk of bias tool were used to assess the quality and risk of the studies, respectively. The protocol was registered in PROSPERO (code: CRD42023449627). Of the 423 records initially found, 13 were finally included in the systematic review, in which 349 adults with DS participated. 92% of the articles declared at least one significant difference post-intervention. The available evidence indicates that exercise, physical activity, and sports have a positive effect on some variables of physical fitness, especially strength, balance, body composition, cardiorespiratory fitness, flexibility, and functional capacity. Furthermore, it should be considered as an additional treatment or complementary therapy to improve the functionality and quality of life of adults with DS.

Effects of a home-based exercise combined yoga and resistance training in enthesitis-related arthritis in China: study protocol for a randomised controlled trial

INTRODUCTION

Enthesitis-related arthritis (ERA) is a category of juvenile idiopathic arthritis (JIA). The complications of JIA include pain, muscle weakness, limited movement and worsening quality of life. Yoga is an effective exercise therapy for rheumatoid arthritis and may have similar benefits for JIA. Considering the limitation of yoga for strengthening muscles, combined yoga and resistance training (CYRT) may compensate for the shortcomings and provide more benefits for JIA patients. Despite this, there is currently a lack of studies investigating the effectiveness of CYRT for JIA patients. Due to the inaccessibility of traditional exercise therapy, home-based exercise is needed. The study aims to assess the effectiveness of home-based CYRT on JIA.

METHODS AND ANALYSIS

This is a 12-week randomised single-blind controlled trial study. 60 patients with ERA will be randomised into two groups: the home-based exercise group (HBE) and the health education (HE) group. The HBE group (n=30) will perform the CYRT programme 3 times a week at home for 12 weeks and receive HE. The HE group (n=30) will only receive HE. The outcomes include primary outcome (pain levels) and secondary outcomes (lower limb muscle strength, motion range of joint, aerobic fitness, function ability, fatigue levels, mental health, quality of life and blood biomarkers). The assessments will be conducted at baseline, postintervention (12 weeks) and follow-up (24 weeks). Data will be analysed by intention to treat.

ETHICS AND DISSEMINATION

This study has been approved by the Ethics Committee of Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine in December 2023 (approval no. XHEC-C-2023-059-3). This study will require informed consent from all subjects and guardians of children under 18 years of age. The findings will be published in a peer-reviewed journal and international conferences.

Targeting Sarcopenia as an Objective Clinical Outcome in the Care of Children with Spinal Cord-Related Paralysis: A Clinician's View

Muscle loss is consistently associated with immobility and paralysis and triggers significant metabolic and functional changes. The negative effects of sarcopenia are amplified in children who are in the process of building their muscle mass as part of development. Because muscle mass loss is consistently associated with increased morbidity and mortality throughout life, optimizing the size and health of muscles following a neurologic injury is an objective target for therapeutic interventions. This review hypothesizes that muscle mass correlates with functional outcomes in children with paralysis related to spinal cord-related neurologic deficits. We propose that the measurement of muscle mass in this population can be used as an objective outcome for clinical long-term care. Finally, some practical clinical approaches to improving muscle mass are presented.

Effects of a 12-week, seated, virtual, home-based tele-exercise programme compared with a prerecorded video-based exercise programme in people with chronic neurological impairments: protocol for a randomised controlled trial

INTRODUCTION

Exercise is vital to staying well and preventing secondary complications in people with chronic neurological impairments (CNI). Appropriate exercise is often inaccessible to this population. The purpose of the study is to investigate the effects of a seated, virtual exercise programme on heart rate, recovery, fatigue, pain, motivation, enjoyment and quality of life in people with CNI.

METHODS AND ANALYSIS

Individuals with CNI will be screened for eligibility, and 60 participants will be randomised 1:1 into either a live or prerecorded group. There is no geographical limitation to where participants reside, since participation is virtual. The study will be coordinated by one site in White Plains, New York, USA. The live group will exercise with an instructor via Zoom while the prerecorded group will exercise at their chosen time using prerecorded videos, 3×/week for 12 weeks.

PRIMARY OUTCOME MEASURES

change in heart rate during exercise/recovery.

SECONDARY OUTCOME MEASURES

fatigue, motivation, level of pain and exertion, physical well-being, enjoyment of physical activity, motivation and quality of life. Outcomes will be assessed at baseline, midpoint, end of study and 1-month poststudy. Adverse events, medication changes and physical activity will be tracked throughout. Within-group and between-group comparisons will be performed by using analysis of covariance and regression.

ETHICS AND DISSEMINATION

BRANY IRB approval: 22 September 2020, protocol #20-08-388-512. All participants will provide written informed consent. Results will be disseminated through presentations, publications and ClinicalTrials.gov.

Regulatory Mechanisms of Muscle Mass: The Critical Role of Resistance Training in Children and Adolescent

Muscle mass and strength are subjected to several regulations. We found endocrine signals such as growth hormone, insulin-like growth factor 1, testosterone, thyroid hormones, and glucocorticoids among them. Neural inputs also influence muscle development, modulating mass and strength. Among the external stimuli that modulate these muscular features is physical training such as resistance and endurance training. Specifically, resistance training can mediate an increase in muscle mass by hypertrophy in adults, but the effects in children and adolescents are full of myths for most of the population. However, the evidence shows that the impact of resistance training on children and adolescents is clear and provides a wide range of benefits. However, qualified professionals must be available since exercise prescription and subsequent supervision must follow this population's abilities, needs, and interests.

Physical Activity Interventions in Children with Juvenile Idiopathic Arthritis: A Systematic Review of Randomized Controlled Trials

Introduction

Children with juvenile arthritis (JA) experience pain, stiffness, fatigue, and decreased motion leading to difficulties with daily activities and low physical activity (PA). PA is critical to improve health and function and mitigate JA-associated symptoms. This study evaluated the evidence for PA interventions in children with JA.

Materials and Methods

A systematic review of randomized controlled trials (RCTs) of PA interventions in children with JA was conducted. Ovid (Medline), Cochrane Library, EMBASE, and CINAHL databases were searched for papers published in English between 1/1/1946 and 9/1/2021. Studies which concurrently assessed medical interventions were excluded. Participant and intervention characteristics and outcomes were extracted. Study internal validity and intervention attributes were assessed.

Results

A total of 555 studies were identified, with 13 studies from 10 countries included. Data from 672 children diagnosed with juvenile idiopathic arthritis (JIA) (range of mean ages, 8.7 to 16.1 years) were analyzed. Fifty-two percent of intervention arms incorporated strengthening exercise alone or combined with other exercise, with 61.9% performed 3x/week. About 43.5% of sessions lasted >45 to ≤60 minutes and 65.2% of programs were ≥12 to <28 weeks. PA interventions improved function and symptoms without adverse events. Intervention details were missing especially regarding PA intensity, reasons for dropouts, and adherence. Only two studies incorporated strategies to promote adherence.

Discussion

RCTs of PA interventions in JA only include JIA. Available RCTs used mixed modes of interventions. Reporting of PA interventions lacks sufficient detail to discern the dose-response relationship. Strategies to motivate engagement in PA and to support families to promote PA are lacking, as are studies of long-term outcomes.

Conclusion

There are limited RCTs of PA interventions in JIA. Adherence was better with low intensity programs. PA interventions for JIA yield positive health benefits but better reporting of PA intervention details is needed to generate more high-quality evidence and inform clinical practice.

Effects of Resistance Training in Muscle Mass and Markers of Muscle Damage in Adults with Down Syndrome

Recent studies have emphasized that regular exercise should be encouraged as a key part of care and support for people with Down syndrome (DS). However, muscle hypotonia has traditionally been considered a major barrier to resistance training (RT) in people with DS. The main objective of this study was to analyze the impact of circuit RT on markers of muscle damage. The secondary objective was to assess the influence of a RT program on body composition and work task performance. Thirty-six men with DS were recruited and randomly assigned to perform a circuit RT program with six stations 3 days/week for 12 weeks (n = 18) or to a control group (n = 18). Body composition was assessed by bioelectrical impedance analysis. Serum markers of muscle damage (creatine kinase, myoglobin, and lactate dehydrogenase) were determined at baseline and at the end of training weeks 1, 6, and 12. Work task performance was assessed using the weighted pail-carry test. RT did not induce significant changes in markers of muscle damage during the intervention. Furthermore, muscle mass and work task performance were significantly improved in the exercise group. These findings suggest that circuit RT can be used safely to increase muscle mass and work task performance in young adults with DS. Muscle hypotonia should not be considered a major barrier to exercise in people with DS, provided that qualified staff design and supervise all training sessions.
